TLDR
In this paper, an empirically derived relationship between the chemical composition of a carbonate in the CaCO3-(Ca, Mg)(CO3)2-FeCO3 system and the function 103 In α at 100°C is 103 ∆ α = 8.94XCaCO3 + 9.29XMgCO3+ 8.77XFeCo3 where Xi is the mole percent of component i in the carbonate.About:

Improving the routine analysis of siderite for δ13C and δ18O in environmental change research
TL;DR: In this paper , the authors examine procedures for the isotope analysis of siderite and discuss factors potentially contributing to inconsistencies in sample measurement data, including the absence of international reference materials and mineral-specific acid fractionation factors.

An epigenetic magnesite deposit in the Bergslagen area, central Sweden
TL;DR: A Palaeoproterozoic magnesite deposit in the Bergslagen ore province in Sweden is characterized in terms of petrography and major element, trace element and stable isotope compositions.

Origin of the Hukh Tag Manganese Ore Manifestation (Mongolia): Evidence from Carbon and Oxygen Isotopic Compositions
TL;DR: In this article, the results of the study of mineral, chemical, and isotopic compositions of carbonate rocks and ores from the Hukh Tag manganese ore manifestation suggest its hydrothermal origin.

First record of lower – Middle Ordovician (Tremadocian – Dapingian) carbon isotope (δ13Ccarb) chemostratigraphy in the Canning Basin, Western Australia; calibrated with geochronology/biostratigraphy and implications for global correlations
TL;DR: In this paper, stable carbon isotope data (δ13Ccarb and δ18Ocarb) from petroleum exploration well Olympic 1 in the Canning Basin, Western Australia are presented.

Carbon- and Oxygen-isotope Stratigraphy: A Tool for Confirming Sequence Stratigraphy in the Early Triassic Kangan Formation, Northern Part of the Arabian Plate
TL;DR: The Early Triassic Kangan Formation (KG1 to KG3) is the main reservoir for natural gas in southwest Iran and the northern Gulf as mentioned in this paper, which is composed of 14 facies deposited in tidal flat, lagoon and oolitic barrier settings.

Isotopic standards for carbon and oxygen and correction factors for mass-spectrometric analysis of carbon dioxide
TL;DR: In this paper, Niee's and Solenhofen standards were compared to the Chicago PDB standard for carbon and oxygen isotope ratios, and the correction factors for instrumental effects and for the nature of the mass spectra were derived.

On the Isotopic Chemistry of Carbonates and a Paleotemperature Scale
TL;DR: In this paper, the temperature variation of the fractionation of oxygen in exchange reactions between dissolved carbonate and water and between calcite and water was calculated on theoretical grounds, and checked experimentally.

The use of bromine pentafluoride in the extraction of oxygen from oxides and silicates for isotopic analysis
TL;DR: In this paper, a technique was developed in which bromine pentafluoride was used as a reagent for quantitative liberation of oxygen from oxides and silicates, and the results of isotopic analyses were compared with measurements made in other laboratories by other procedures.
Journal ArticleDOI
Measurement of O18O16 ratios of total oxygen of carbonates
TL;DR: The commonly used phosphoric acid procedure for the determination of oxygen isotope abundances in carbonates involves a large kinetic isotope effect as mentioned in this paper, which leads to an overestimate of the dolomite-calcite oxygon isotope fractionation by 0.8 per mil.
